What is a Chilled Ceiling?
A chilled ceiling is a type of convection system designed to cool workspaces and the like. Often, they are integrated into the suspended ceiling system. A chilled ceiling is piped to allow chilled water circulation through the ceiling to thermally affect the room air. As the air becomes denser and falls to the floor. It is replaced by warmer air moving up from, causing a constant passive air movement called convection, which cools the room. But as the pipes lie behind metal ceiling plates it is actually the cooled plates that are the cause of convection and not the pipe unit itself. Therefore, chilled ceilings are less effective in comparison with chilled beams.
Chilled ceilings are commonly seen in office areas, wards and other similar facilities and both pipe size and flow rates are normally in the lower end.
How is a Chilled Ceiling Application Optimized?
A chilled ceiling will - with proper balance on the water - reduce flow to design requirements and save energy. FlowCon recommends three different solutions to a chilled ceiling installation:
1. Chilled Ceilings with Pressure Independent Control (PICV)
The PICV will react to system pressure changes and regulate the flow of water to required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.
FlowCon recommends the following PICVs:
2. Chilled Ceilings with Temperature Control (TCV)
The TCV will react to system pressure changes and automatically provide the selected max. flow independent of pressure changes. In addition, the actuator will provide ON/OFF control, securing proper thermal performance always, even at partial loads.
FlowCon recommends the following TCV:
3. Chilled Ceilings with Automatic Balancing (ABV)
The automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to required max. flow helping the system to be accurately controlled even with pressure changes. This solution may be installed with the separate control valve.
FlowCon recommends the following ABVs:
